First attempt at oversead

I made a good number of learning mistakes for the first few years of lawn ownership I am now starting to fix section by section. This past fall I scalped, de thatched, aerated (which it was too dry for so didn't do much), overseaded with KBG, seedling fertilizer/weeder, topdressed with peat moss, and watered with Orbit H2O gear drive (best sprinkler ever) on a timer. It's not perfect but it's soooo much better. Now my issue is it grows faster than I can mow it.
